ABSTRACT:
A method is provided for preparing a diamond coating on a substrate. The method includes a first step of applying a partial diamond coating having an effective amount of void area therein to the work surface of a substrate. In a follow-up step the void area in the partial coating is filled with binder, preferably metallic binder. In a later step, diamond projecting outwardly from the binder is further grown, to generate a covering portion or a head portion extending over, and in protective relationship with, the binder or binder material. According to the present invention preferred products are also provided.
